Abstract (en)
[origin: US2015301318A1] The invention provides an optical imaging lens assembly comprising, in order from an object-side to an image side, a first aspherical positive lens element and a second aspherical negative lens element, each comprising an object-side surface and an image-side surface. Elements of the optical imaging lens assembly may be configured to satisfy the relations (i) T<1.2 f, (ii) 1.1<f/f1<1.5, (iii) −1.5<f/f2<−0.6, (iv) 0.2<R1/f<0.5, and (v) −0.25<K1<−0.05, wherein f is focal length of the lens assembly, f1 is focal length of the first lens element, f2 is focal length of the second lens element, R1 is radius of curvature on the object-side surface of the first lens element, K1 is conic of the object-side surface of the first lens element, and T is total track length of the optical lens.
